NEW QUESTION # 182
Which two statements are true?

• A. CASE is a function and DECODE is not.
• B. DECODE is a function and CASE is not.
• C. All conditions evaluated using CASE can also be evaluated using DECODE.
• D. AIl conditions evaluated using DECODE can also be evaluated using CASE.
• E. Both CASE and DECODE are functions.
• F. Neither CASE nor DECODE is a function.

Answer: B,D

Explanation:
A). True. The DECODE function can evaluate conditions, but it is limited to equality checks. On the other hand, CASE can evaluate these and a broader range of conditions using different comparison operators.
D). True. DECODE is a function in Oracle SQL that allows for simple conditional query transformation.
CASE is not a function but a statement that provides more flexibility and readability when handling conditional logic in SQL queries.
DECODE is more limited compared to CASE since it can't perform logical operations other than equality.

NEW QUESTION # 183
Which statements are true regarding primary and foreign key constraints and the effect they can have on table data?

• A. It is possible for child rows that have a foreign key to be deleted automatically from the child table at the time the parent row is deleted.
• B. It is possible for child rows that have a foreign key to remain in the child table at the time the parent row is deleted.
• C. A table can have only one primary key and one foreign key.
• D. Primary key and foreign key constraints can be defined at both the column and table level.
• E. Only the primary key can be defined the column and table level.
• F. A table can have only one primary key but multiple foreign keys.
• G. The foreign key columns and parent table primary key columns must have the same names.

Answer: A,D,F

Explanation:
Regarding primary and foreign key constraints:
* A. A table can have only one primary key but multiple foreign keys. This is true. A table is constrained to have only one primary key, which can consist of multiple columns, but can have several foreign keys referencing primary keys in other tables.
* C. Primary key and foreign key constraints can be defined at both the column and table level.
True. Constraints can be defined inline with the column definition or separately at the end of the table definition.
* E. It is possible for child rows that have a foreign key to be deleted automatically from the child table at the time the parent row is deleted. This is also true if the foreign key is defined with the ON DELETE CASCADE option.
Options B, D, F, and G are incorrect:
* B is incorrect because if a parent row is deleted, the child rows cannot remain without violating the integrity unless the foreign key is defined with ON DELETE SET NULL or similar behavior.
* D is incorrect because both primary and foreign key constraints can be defined at both levels.
* F is incorrect as the names of the foreign key columns do not need to match the primary key column names.
* G is incorrect as a table can have multiple foreign keys.

NEW QUESTION # 184
View the Exhibit and examine, the description for the SALES and CHANNELS tables. (Choose the best answer.)

You issued this SQL statement:
INSERT INTO SALES VALUES (23, 2300, SYSDATE,
(SELECT CAHNNEL_ID
FROM CHANNELS
WHERE CHANNEL_DESC='DIRECT SALES'), 12, 1, 500);
Which statement is true regarding the result?

• A. The statement will fail because the VALUES clause is not required with the subquery.
• B. The statement will fail because a subquery cannot be used in a VALUES clause.
• C. The statement will execute and a new row will be inserted in the SALES table.
• D. The statement will fail because the sub-query in the VALUES clause is not enclosed within single quotation marks.

Answer: C

NEW QUESTION # 185
Which two statements are true about an Oracle database? (Choose two.)

• A. A table can have multiple foreign keys.
• B. A VARCHAR2column without data has a NULLvalue.
• C. A NUMBERcolumn without data has a zero value.
• D. A table can have multiple primary keys.
• E. A column definition can specify multiple data types.

Answer: A,C

NEW QUESTION # 186
Examine this statement:

Which two things must be changed for it to execute successfully?

• A. The primary key constraint on BMP_ID must have a name.
• B. The NOT NULL constraint on ENAME must be defined at the column level instead of the table level.
• C. The word CONSTRAINT in the foreign key constraint on DEPT_ID must be changed to FOREIGN KEY.
• D. The foreign key constraint on DEPT_ID must be defined at the table level instead of the column level.
• E. One of the LONG columns must be changed to a VARCHAR2 or CLOB.

Answer: B,E

Explanation:
The statement is trying to create a table with columns of different data types and constraints. Here's what needs to be corrected:
* C: In Oracle, the LONG data type is used for character data of variable length up to 2 Gigabytes, but it is deprecated, and you should use CLOB or VARCHAR2 instead. Furthermore, a table cannot have more than one LONG column.
* D: The NOT NULL constraint should be specified at the column level, not at the table level. The correct syntax for creating a table with a NOT NULL constraint is to define it inline with the column definition, like this:
ename VARCHAR2(15) CONSTRAINT ename_nn NOT NULL,
The other options are incorrect:
* A: The foreign key constraint syntax is correct; the word CONSTRAINT is followed by the constraint name and then the REFERENCES clause.
* B: The foreign key constraint can be defined at the column level.
* E: While it's a good practice to name constraints, it is not mandatory for the primary key constraint to have a name; Oracle will generate one if it's not provided.

NEW QUESTION # 187
Examine this SELECT statement and view the Exhibit to see its output: (Choose two.)

SELECT constraints_name, constraints_type, search_condition, r_constraints_name, delete_rule, status, FROM user_constraints WHERE table_name = 'ORDERS'; Which two statements are true about the output?

• B. The DELETE_RULE column indicates the desired state of related rows in the child table when the corresponding row is deleted from the parent table.
• C. The STATUS column indicates whether the table is currently in use.
• D. In the second column, 'c' indicates a check constraint.

Answer: B,D

NEW QUESTION # 188

FROM orders;
Which statement is true regarding the above command?

• A. The NEW_ODRDERS table would not get created because the DEFAULT value cannot be specified in the column definition.
• B. The NEW_ODRDERS table would get created and only the NOT NULL constraint defined on the specified columns would be passed to the new table.
• C. The NEW_ODRDERS table would get created and all the constraints defined on the specified columns in the ORDERS table would be passed to the new table.
• D. The NEW_ODRDERS table would not get created because the column names in the CREATE TABLE command and the SELECT clause do not match.

Answer: B
